THlLL-COUPLlNG'.

SPECIFICATION forming part of Letters Patent No. 274,656, dated March 27, .1883.

' i Application filed September 16, 1882. (N model.)

To all whom it may concern Be it known that I, NELsoN. A. Pnnvrus, of Somerville, in the county of Middlesex, of the State of Massachusetts, have invented a new and useful Improvement in Carriage Thill Couplings; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- I Figure 1 is a top view, Fig. 2 a vertical and longitudinal section, and Fig. 3 a horizontal and longitudinal section, of a thill-coupling em .bodying my invention, the nature of which is dulydefinedin the claimshereinafter presented. Fig. 4 is an end elevation of it. Fig. 5 is a top view of the journal and its carrier, as hereinafter described.

In the said drawings, A denotes an ordinary thill-clip, provided with screws a a and nuts b b, andhaving projecting from it a right-angular-shaped bearing-piece, B, which atits inner end is provided with a tenon, 0, having a screw, 0, extending from it, in manner as represented. This tenon goes through a journalcarrier, D, provided with a cylindrical jour- 119.1, E, extended from it at a right angle, and going through the cylindrical head d of a thill coupling iron, E, and into the bearing-piece B. This coupling-iron turns freely on the journal and against an elastic block,'G, of indie-rubber, arranged with it and in the bearing-piece B, in manner as represented. At its rear the block G' rests against an adjustable bearing-plate, H, provided at its middle with a screw, I, that extends from it in manner as represented, and goes into a hole, h, in the bearing-piece B. Arranged within a mortise, i, made in the bearing-piece B, and screwed upon the screw I, is a nut, K.

On revolving the nut one way upon the screw the plate H will be forced against the block G and crowd it firmly against the thill-iron head,

which, by turning against the block, is prevented from rattling on the journal. The carrier is held in place not only by the journal, but by a nut, L, screwed on the screw 0, such nut serving to force the carrier against the block G. This block, by its elasticity, operates to keep both of the nuts K and L from acciden t ally working loose or turning upon their screws.

From the abor e it will be seen that as the elastic block G may become worn by the thilliron head it (the said block) may be forced up to the said head by the nut; also, that the separation of the thill or connecting of it with thecarriage can, by the above described coupling. be effected very easily and expeditiously.

I claim as my invention- 1. The combination ot'aclip and hearing-piece B, provided with the screw-tenon O, extending from it, as shown, with the journal-carrier D and the journal E, arranged as represented, such carrier having the screw-tenor] extending through it, and also having the journal projected within the bearing-piece, and all being substantially as represented.

2. The combination of the bearing-plate Ll, itSSGIBW I, andtuut K, with the hearing-piece B, and with the carrier D and the journal E, arranged with and adapted to the bearingpiece substantially in manner as set forth, the said plate H being to operate, as described, against the elastic or rubber block G, placed against the thill-iron headand in the bearingpiece and against the plate H, in the manner Witnesses:
